To all whom it may concern:

Be it known that I, JoirN FnrenN, a citizen of the United States, and a resldent of ment layer'lQ.

The object of this invention is to provide In the lirst plaro. the pallet of the mold a veneer building heard or block, to take is coated with a binder and crushed granite the place of brick or stone in the conis sprinkled nll said hinder and then the' struction of buildings, and which is socon ballot is turned upside down so that the 15 structcd as to have a hard or granite exparticles of granite not hound hy the binder ternal surface, andyet the board or block fall away.

Therefore, this building boardis put in lace on the outside of a house somewhat li e other kinds of building board, or secured on the inside oi the house; but this makes the outer veneer ofa wall of a permane t character. a blow will cause a slight dent without breaking the external surface, as the material behind the external surface yields somevfat to the blow. If any particular board should be injured while erecting the wall, or afterward, it can be readily removed without displacing the other boards, and a new board put in place without difliculty. This is a peculiar advantage of this sort of building board. It is, furthermore,

much cheaper than veneernbricks or stone,

for which it is a substitute. With such granite-coated building boards, a wall of very attractive appearance will result, andit will resist temperature from the outside changes, rain, and thelike, eflectively.
